Sulfur autotrophic denitrification (SAD) process has significant potential in treating low carbon/nitrogen ratio wastewater. However, the presence of zinc ions (Zn) adversely affects the denitrification performance. This study investigated the effect of biochar prepared at 300 °C (BC300) and 600 °C (BC600), as well as dosing strategy, on denitrification performance in the SAD process under Zn inhibition.

Background: Gallbladder mixed neuroendocrine-non-neuroendocrine neoplasm generally consists of a gallbladder neuroendocrine tumor and a non-neuroendocrine component. The World Health Organization (WHO) in 2019 established a guideline requiring each component, both neuroendocrine and non-neuroendocrine, to account for a minimum of 30% of the tumor mass.

Methods: Patients after surgery resection and diagnosed at microscopy evaluation with pure gallbladder neuroendocrine carcinoma (GBNEC), gallbladder mixed adeno-neuroendocrine carcinoma (GBMANEC, GBNEC≥30%), and gallbladder carcinoma mixed with a small fraction of GBNEC (GBNEC <30%) between 2010 and 2022 at West China Hospital of Sichuan University were collated for the analyses.

Sulfur-driven autotrophic denitrification (SAD) process is a cost-effective and sustainable method for nitrogen removal from wastewater. However, a higher concentration of zinc ions (Zn(II)) flowing into wastewater treatment plants poses a potential threat to the SAD process. This study examined that a half maximal inhibitory concentration (IC) of Zn(II) was 7 mg·L in the SAD process.

Article Synopsis
  • Intrahepatic cholangiocarcinoma (ICC) is a serious type of cancer that affects the liver, and researchers are trying to understand how the tumor environment interacts with different cells.
  • They used a special method to find out which genes are important in the tumor and how cells communicate with each other.
  • The study found that certain gene scores related to cancer cells can predict how well patients will do, and they discovered specific ways that certain cells interact, which might help in developing better treatments.

The platelet to lymphocyte ratio (PLR) is the marker of host inflammation and it is a potential significant prognostic indicator in various different tumors. The serum carbohydrate antigen 19-9 (CA19-9) is a tumor-associated antigen and it is associated with poor prognosis of gallbladder cancer (GBC). We aimed to analyze the prognostic value of the combination of preoperative PLR and CA19-9 in patients with GBC.

Sulfur-driven autotrophic denitrification (SAD) exhibits significant benefits in treating low carbon/nitrogen wastewater. This study presents an eco-friendly, cost-effective, and highly efficient method for enhancing nitrogen removal performance. The addition of biochar prepared at 300 °C (BC300) notably increased nitrogen removal efficiency by 31.

Background: The neutrophil-lymphocyte ratio (NLR) and platelet distribution width (PDW) are associated with poor prognosis in various cancers. We aimed to analyze the prognostic value of the combination of preoperative NLR and PDW in patients with gallbladder carcinoma (GBC).

Methods: A total of 287 GBC patients who underwent curative-intent surgery in our institution was included.

Background: The application of three-dimensional (3D) reconstruction has been extensively adopted in hepatectomy navigation, yet its utilization in laparoscopic radical resection of perihilar cholangiocarcinoma (pHCCA) remains underexplored.

Video: A 54-year-old male patient, classified as Child-Pugh B, presented a small neoplasm situated at the left hepatic duct proximate to the right hepatic and common hepatic ducts. An enhanced abdominal computed tomographic scan identified a solitary lesion measuring 2.

Sulfur-driven autotrophic denitrification (SAD) granular process has significant advantages in treating low-carbon/nitrogen wastewater; however, the slow growth rate of sulfur-oxidizing bacteria (SOB) results in a prolonged start-up duration. In this study, the thiosulfate-driven autotrophic denitrification (TAD) was successfully initiated by inoculating anaerobic granular sludge on Day 7. Additionally, the electron donor was successfully transferred to the cheaper elemental sulfur from Day 32 to Day 54 at the nitrogen loading rate of 176.

Background: Combined hepatocellular carcinoma and cholangiocarcinoma (CHCC-CC) is a rare subtype of primary liver malignancy and has been treated equally as intra-hepatic cholangiocarcinoma (IHCC) according to the 8th AJCC staging system. Owing to its rarity, its prognostic factors have been rarely explored and defined.

Methods: PubMed, EMBASE, the Cochrane Library and Web of Science were searched up till January 1st, 2023 and eligible studies were restricted to studies reported prognostic factors of resected CHCC-CC.

Article Synopsis
  • Nucleolus is a key cellular organelle, with its shape and number being potential indicators of various human diseases.
  • A series of fluorescent probes (NI-1 to NI-5) based on naphthalimide derivatives have been developed to improve imaging of the nucleolus, successfully staining living cells.
  • These probes demonstrated enhanced fluorescence when binding to RNA due to specific interactions, which could aid future diagnosis and treatment of diseases linked to the nucleolus.

Outcomes of laparoscopic liver resection (LLR) versus open LR (OLR) for intrahepatic cholangiocarcinoma (ICCA) are heterogeneous. We aimed to compare LLR and OLR for ICCA based on propensity-score-matched (PSM) studies. Two reviewers independently searched the online databases (PubMed, Embase, and Cochrane Library) for PSM studies that compared LLR and OLR for ICCA.

Background: Tumor necrosis has been indicated to correlate with dismal survival outcomes of a variety of solid tumors. However, the significance and prognostic value of tumor necrosis remain unclear in gallbladder carcinoma. The aim of this research is to explore the relationships between necrosis with long-term survival and tumor-related biological characteristics of patients with gallbladder carcinoma.

Article Synopsis
  • Gallbladder neuroendocrine carcinoma (GBNEC) is a rare and poorly differentiated tumor, and its clinical characteristics compared to gallbladder adenocarcinoma (GBADC) are debated.
  • In a study of 201 GBADC and 36 GBNEC cases, GBNEC patients were found to be younger and more likely to present with advanced tumor stages, as well as higher rates of perineural invasion (PNI) and lymphovascular invasion (LVI).
  • Although GBNEC patients initially showed worse survival outcomes than those with GBADC, after matching for various factors (propensity score matching), their overall and recurrence-free survival rates were similar, with significant pathological features influencing prognosis instead.
